I am really interested in this guy. I told him I like him and he said he thought I was cute but he was in a mono relationship right now and would still like to talk to me and get to know me. I still want to get to know him and be friends with him, but he takes days to reply or even a week. (usually I have to send him a message again when he is online so he replies)
I don't have his number so I can't text him. He does have social media, but doesn't have the apps for it so he uses his laptop. On fb people usually click the blimps and forget about whether someone messaged them or there is a notification. I do that too. I don't know how to talk to this person if we can't even meet in real life (no common ground, no same classes or anything)
Question: How do I make plans to talk to them and get to know them if they don't use social media that much?
EDIT: I mentioned more information in the comments so here is that information: I met him on the dating app while they were poly.
